Blake Lively Shows Off Her Amazing Body in First Post-Baby Bikini Shots

The 28-year-old statuesque blonde was recently snapped on the set of her latest film, The Shallows, on Lord Howe Island in New South Wales, Australia, rocking a bold orange bikini. Going barefoot in the sand and sporting a casual braid in her hair, Blake looked as gorgeous as ever.

Blake's husband, 39-year-old Ryan Reynolds, and their daughter, 10-month-old James, were also on set to spend time with the actress. "Ryan was just hanging with James and chatting while Blake was filming," a source tells ET. "The two seemed really happy. Blake was in a really good mood."

The Shallows stars Blake as a woman stranded alone on a buoy with a great white shark circling the waters between her and the shore. The thriller is set to debut next June.

The former Gossip Girl star has made no secret about working out to get her enviable bikini bod, giving a shout-out to her trainer, Don Saladino, in September. "This fit dude, @donsaladino NOSE how to kick my butt. #WhyIsCelluliteIsSoMuchCuterOnBabies," she wrote.

ET caught up with the celebrity trainer himself in September, when Saladino gushed about one of his most famous clients.

"Blake Lively does not have cellulite. I can say that!" he said, despite her modest hashtag. "Blake loves to train the legs and the abs. She wants strong arms and strong shoulders, so that's something that we incorporate into a full-body workout."
